PORTABLE STOCK-YARD.

Specification of Letters Patent.

Application filed March 26, 1913. Serial No. 756,931.

To all whom it may concern:

Be it known that I, THOMAS J. HAWKINS, a citizen of the United States,residing at Guthrie, in the county of Todd and State of Kentucky, haveinvented new and useful Improvements in Portable Stock-Yards, oi whichthe following is a specification.

This invention relates to improvements in building construction and hasfor its object to provide improved means of connecting a plurality ofsections of a partition wall.

In carrying out my invention use is made of novel locking means forconnecting together a number of wall plates which are adapted togetherto form a continuous partition or siding of a building structure, and tothis end my improvement is directed to a knock down structure whichconsists of a minimum number of parts, which can be set up and assembledwith all. of its constituent parts by any person without skill, andadmits of being readily disconnected without considerable trouble andannoyance.

With the above and other objects in view, my invention consists in thecombination, arrangement and details of construction disclosed in thedrawing and specification, and more particularly pointed out in theappended claim.

In the drawing :Figure 1 is a fragmentary side elevation of adjacentlike sections, the

same being partly in section, Fig. 2 is a similar view showing a novelform of lock, Fig. 8 is a front elevation, partly in section, of theknock down sections in assembled position, and Fig. 4 is a fragmentaryview of a section of a partition taken at right angles to Fig. 3.

Referring to the drawings which are merely illustrative of my invention,a plurality of knock down sections which may be called. center sections21 are adapted to be connected by means now to be explained. Each ofthese sections is formed from parallel rails'or angle uprights 23 insuch a manner that the meeting edges of adjacent uprights 28 areconnected together by means of locks 24:. Each of these looks consistsof a bolt passing through one side-of the angle iron upright of asection of a partition wall, and having a head 26 abutting the Same andthe bolt is also provided with an enlarged body portion 27 while oneside of the angle iron upright of an adjacent section is pro vided withan opening 28 of a greater length than the length of said body portion27, and through this opening the body portion is adapted to project soas to rest upon the lower edge 29 of said opening and to be spaced apartfrom the upper edge 30 of said opening. In this way the withdrawal ofthe bolt from the slot is effectively prevented. There is an arm 31pivoted upon the side of each angle iron upright which is formed withthe said opening 28, the function of which is to force the body portionof the lock to occupy a position so as to prevent the body portionengaging the upper edge of the opening. This is accomplished, by causingthe free end of said arm 31 to engage the upper end of the body portionthereby looking it against reverse movement. Besides the body portion ofthis look may have a tendency to withdraw the hook bill 32 which engagesthe angle iron of the upright against which the head of the bolt bearsas clearly shown in Fig. 2.

It will be seen from the foregoing explanation that the knock downsections are connected by means of locks in such a manner that, in orderthat the sections may have their angle iron uprights contacting so as tobe suitably connected, one section is slightly raised above the othersection so as to enable the body portion of the locking bolt to passthrough the opening formed in the opposite section and when this hasbeen done the first section is brought down to a common level with theother section until the body portion of the bolt rests upon the loweredge of the openin and will engage the look only when the body portionis being' initially introduced. The pivotal arm is pressed with its freeends against said body portion to prevent either section being raisedrelatively to the other. When the pivotal arm is removed from contactwith the bolt the sections may be raised and moved in a manner whichwill be understood.

It is intended to claim all reasonable modifications coming within theview of the structure claimed.

I claim A partition wall formed of a plurality of adjoining sections,each section comprising an angle iron frame, one leg of the angle ironforming the edge of the section and the other leg extending inwardly,one vertical edge of each section having secured thereon 2 V V V r1,187,990
